Abstract
Description
図1は本発明の一実施形態に係るローラレベラを示す側面図、図2はその正面図である。本実施形態のローラレベラ100は、ハウジング1と、ハウジング1の内側に設けられた上フレーム2と、ハウジング1を支持するように設けられた下フレーム3とを有している。上フレーム2の下方には上ロールフレーム5が上ロールグリップシリンダ(図示せず)で吊り下げられている。一方、下フレーム3上には下ロールフレーム10が設置されている。なお、上フレーム2は、後述するように、押圧シリンダ(圧下シリンダともいう)によって押すことによって上下に動作するため、作動フレームと呼ぶことができる。作動フレームは上フレーム2に限定されず、下フレーム3を作動フレームとして構成してその下に設けた押圧シリンダによって押すことによって上下に動作させることもできる。
なお、本明細書において、「圧下」という用語は、図1に示すように圧力を下向きに加える場合だけでなく、後に変更例として説明するように圧力を上向きに加える場合も包含することを意図する。換言すれば、本明細書において、「圧下」という用語は、「押圧」という用語に置き換えることができる。
制御装置50は、コンピュータ読み取り可能な記憶媒体に記憶された制御プログラムに従って、後述するように、板材Pの矯正(レベリング)のための圧下シリンダ4a,4bによるレベリングロール6,8の圧下量の制御、駆動装置15の制御を行うようになっている。また、制御装置50には撓み検出センサ21、22からの情報およびロードセル23からの情報が入力され、これら情報に基づいて圧下シリンダ4a,4bを制御することによるフレームの縦撓み補正、油圧式クラウニングシリンダ12の絞り込み制御によるフレームの横撓み補正および圧縮補正が行われる。
ローラレベラにおいては、矯正反力によりハウジング1に上下方向(縦方向)の撓み(縦撓み)を生じるため、このような縦撓みを補正する必要がある。従来は、板材の中心をライン中心に位置させた対称レベリングであったため、縦撓み補正制御において、入側の圧下シリンダおよび出側の圧下シリンダについて、入側矯正反力Feおよび出側矯正反力Fdのいずれも、ワーク側(WS)とドライブ側(DS)の和荷重を用い、これら入側矯正反力Feおよび出側矯正反力Fdと、ハウジングのミル定数:K1および入側圧下シリンダのミル定数および出側圧下シリンダのミル定数:K2と、機械手寸法による定数を用いて、入側および出側の縦撓みを計算し、入側圧下シリンダ4aおよび出側圧下シリンダ4bの締め込み量(位置)を制御していた。したがって、入側も出側も、板幅方向のワーク側(WS)とドライブ側(DS)とで同じ縦撓み値を用いていた。
δW=(FW+FD)f(α)/K
δD=(FW+FD)(1-f(α))/K
ただし、f(α)はオフセット量αの関数、Kは圧下シリンダのミル定数
そして、入側圧下シリンダ4aおよび出側圧下シリンダ4bとも、これらδW、δDの値が0になるようにワーク側(WS)の圧下シリンダ4aW、4bWおよびドライブ側(DS)の圧下シリンダ4aD、4bDの締め込み量(位置)を非対称制御する。
ローラレベラにおいては、矯正反力により、上下フレーム2,3に幅方向の撓み(横撓み)が生じるため、このような横撓みを補正する必要がある。従来は、板材の中心をライン中心に位置させた対称レベリングであったため、横撓み補正制御において、幅方向中央に設けた撓み検出センサの検出値に基づいて幅方向の各位置の撓み量を算出し、それを各位置での横撓み補正値とし、それに基づいて各油圧式クラウニングシリンダ12の締め込み量を算出していた。

ローラレベラにおいては、矯正反力により、油圧式クラウニングシリンダ12、上ロールフレーム5、上バックアップロール7、上レベリングロール6、下レベリングロール8、下バックアップロール9、下ロールフレーム10に圧縮変形が生じるため、このような圧縮変形を補正する必要がある。従来は、板材の中心をライン中心に位置させた対称レベリングであったため、入側および出側の圧下シリンダの荷重をロードセルで検出し、これにより油圧式クラウニングシリンダの入側と出側の反力を計算して、その計算値から入側と出側の圧縮変形のミル定数を求め、これらの値から板幅中心の圧縮変形量すなわち補正量を算出し、比例計算により板幅各位置での補正値を算出し、それに基づいて各油圧式クラウニングシリンダの締め込み量を算出していた。
